Be it known that I,"AN GELo Pr mal a cit'i zen of the United. States,residing at Watertown, in the county Off- Ml(ldl6S8X2tIl(l State of'Massa'chusetts, have invented Icertain new and useful lmprovenients in Shoe-Heeling Methods, ofz.which the following is 1a specification, reference being hadftherein' to the accompanying drawing. f

improved shoe heel- I on the parallel :nail' tops.

This "invention 1s an ing method. Inpart the presentinvention embodies amethod and produces a product similar to my prior, Patent 1,289 ,O 5 4,*pat ented DecemberQL, 191 8, and in part is an improvement thereover. ject of, the present invention therefore is to improve the method of preparing'and at-' taching heels to shoes. The more particular objects and advantages will be made clear inthe hereinafter following description of one illustrative embodiment of the inven-. tion, or will be apparent-to those skilled in the art.- To the attainment of such objects and advantages, the present invention consists in ,the novel features of method, steps, operations and details hereinafterdescribed, illustrated brclziimed. e l

i This application is a division of my prior application Serial No.262,1 0 4, filed November 11, 1918, for heel nailing machine, this application referring more particularly to the method and the prior one to ;the ma chine and mechanism, to whiehja reference is hereby made for amore full disclosure of the preferred mode of carrying out the present invention. i

In the accompanying drawings, which were originally filed as Figures 12 to 20, in-

elusive, of mypatentapplication Serial No. 262,104, Fig. 1 is a side elevation of a builtup heel in the rough. r

Fig. 2 is a similar view, partly broken away, of the same heel after its vertical compression, and the concave shaping of the lower surface or'seat'thereof.

Fig. 3 is a similar view of the same heel, partly broken away, showing the piercing of'a series of short-depth nail holes in a diverging manner.

Fig. 4 is a top plan view of the heel at the stage of the process shown in Fig. 3 but with the piercing awls extracted. Fig. 5 shows the succeeding stage, in which ceding steps and the trimmingw The generalv ob-I driven while'guided by a tapered guide.

g v r 7 heel subsequently 'ap plied; to, the Shoe and the nails further driven straightening of the nailtops into. .parallelism was performedsubsequently to the attachment of the heel to the shoe. In this respect the present invention is -an improvementin that'the bending is performed before the heel is applied, andthis enables" certain operations which are of additional advantage 7 I will now recite more fully the'steps in.-

volved in the"present improvement. Each heel after being properly compressed and shaped, "is preferably first pierced to form a.

series of tapering holes in proper position to receive the'nails. Then, unlike saidprior patent, I prefer to placeagainst'the heel and between thexpierced holes a;t'apering l guideor- 'cone which is to guidethe nails as they are driven. rreferably, the nails are not engaged with the tapering guide until after the latter is in engagement with the heel. Next, the nails are driveninto the heel nearly to the point of emerging at the base. At this point I spread or straighten up the nails. by 'bendin into parallelism.

This is enabled to be rea ily done by simply drawing or lifting off the tapering guide or cone, the baseof which wedges apart the nails as desired. The usual heel nails are not springy and retain their bentposition. A flat guide plate or die may now be laid inside the group of nail tops and the heel laid against'the shoe, and the nailslthen driven and clenched intcriorly, leaving the slightly projecting and parallel nail tops,

upon 'which subsequently the top-lift is forced or drawn, usually after an applica- 7 tion of cement beneath the'top lift.

Preferably the compressing, the piercing, the inserting of the nails, the'partial driving of them, and their bending into parallelism are performed inasingle'machi ne,.and in said parent application as disclosed and clalmed a machlne which performs each of,

and cooperates in all of, these operations After such operations the heel is preferably removed and joined with theshoe and the top lift. I y

Describing the method, Fig. l is a side elevation of a built-up heel20 in .the'rough, The top lift21 is not yet applied, but is seen in subsequent Figs. Sand 9. Preferably the first operation on the rough heel 20 :is its vertical compression, in wvhich the entire heel is reduced in height and the base, or

- what will be termed the underneath side, is.

concavely shaped to formthe surface or heel seat 22, as shown inFig. "2, and adaptedtofit theshoe sole. 'As shown in Fig. 3, a series of short-depth nail holes 23 are next divergingly pierced by awls 24 atthe top side of the;- heel. After the removal-0f the 'awls the heel will. appear as seen in; top

view, .Fig. 4;.3 Next,'a series of nails 25is inserted and driven by drivers acting in the direction of the arrow 26, Fig. 5. The nails are driven not so far as to emerge at the base but so as to leave protruding nail tops 32. According 'to this invention, the space between the series of diverging nails'is pref erably. occupied by a tapering guide 27, the effective surface of which is preferably cone-shaped. Preferablythe: nail tops 32 are bent into the straight-up positions shown at 33 at: this stage of the process,

. rather thanafterattachment to the shoe,

' ing in the direction of the" arrows 28,;Fi'g. 7',

and the stepxis indicated in Fig. 6 as performed by the. lifting of the guide 27, thus causing the separating andstraightening of 7 the nail tops, as stated. The heel may now be detached from the machine and applied to the shoe elsewhere by? driving means act- 7 ,Itwill thus be "present invention.

which" serves to force the nails 'xinto and throughthe shoe outsole 29 and insole'30,

where the nail ends will be suitably clenched V i "at 31. Preferably during this operation thei nail tops-33 will bemaintainedstraight I and upright by adie 35 placed within the series of halls for that purpose. Thereafter, as seen in Fig. 8, vthe top lift 21 is to belaid infplace and driven upon the ishort nail tops 33 by. suitable hammer or .driyer 13.6.
